Electric Blue Marron care sheet
HISTORY: One of the many species of fresh water crustaceans is the Australian Blue Marron, scientific Cherax Cainii.
These crustaceans are often confused with other species, such as normal yabbies, red claws, koonak and gilgie.
However, Australian Marron are indigenous to the south west of Western Australia. They require better quality water than most other fresh water crustaceans. Australia Marron is the largest commercially grown freshwater crustacean.
AQUARIUM MARRON: There have been a few recorded problems encountered with marron living with other fish. Provided there is adequate room for fish and the marron. There must be some landscaping within the tank, to provide territories and shelter. In aquaculture, marron are often poly-cultured with species such as silver perches (with great success!)
Electric blue marron are a colourful addition to your tank, especially since they usually get along with other native Australian fish. However slow moving or bottom dwelling fish should be avoided. Marron will often nip and eat dying or weakened fish.
Aquarium marron contrast well with other Australian fish, thanks to their unique, intense electric blue colour. Their shape, character and behaviour of aquarium marron provide an interesting addition to your aquarium that you cannot achieve with fish alone.
Aquarium marron are entertaining and social and not known to be a burrowing crustacean, so they won’t upset your aquarium’s formation.
We often get chocolate marron mixed in with the electric blue marron and the guys make a great contract to each other!
TANK PREPARATION: It is important to remember Marron can CLIMB – if there is a way to climb out, they will find and escape (NOTE: airlines are an excellent way to assist their escape). Water for marron should be prepared in a similar way to any other fish (i.e. adding water conditioner to remove chlorine)
CARING FOR AQUARIUM MARRON: Marron are a very hardy species. There are several things that can help them to have a long healthy life.
Water salinity level must be kept LOW. They prefer cool oxygen rich fresh water that has been well filtered.
FEEDING: Marron will happily scavenge any unneatened fish food and are omnivorous and will have no problem consuming any commercially available fish food. Sinking pellets are ideal.
